フォーティチュード／極寒の殺人鬼

In season 3, events of recent months have changed everyone in the small Arctic town of Fortitude. Cops, scientists and citizens are all struggling to deal with the fallout from the deaths of Hildur and Munk, the parasite’s malign influence and the vengeful shaman’s rampage. Dan Andersson has lost his way. He survived the parasite, the freezing waters of the Arctic sea, the drug overdose, kidnapping and crucifixion but now the sheriff of Fortitude is struggling to hold onto any sense of good and evil, right and wrong as his own world shifts and fractures. Michael Lennox is drinking himself to death, overwhelmed by grief and failure until a woman from the distant past appears in the town. Elsa Schenthal, responsible for so much calamity. And now she offers Michael a chance at some kind of redemption. And all the time the ghosts of the unquiet dead are flickering at the edges of this frozen, isolated, Arctic world.

In a flashback to a night in the late 1940s with a "blood" Aurora over a Russian camp described as 60 km north of Fortitude, a Russian man discovers another in a tent. There are sounds of bones crunching, and the man in the tent turns to reveal he is devouring a baby. The first man shoots him, only for the man to rise again and walk past him outside. The enraged first man pursues him, shoots him again, but the man again rises and disappears.

A brutal murder is investigated in a small Arctic town.
